PV19 - pink and rose to crimson to violet
PB36 - turquoise and teal to greenish blue
PR101 - transparent burnt orange to granulating burnt orange to earthy red to very opaque earthy red
PBr7 - yellow earth to warm orange browns to dark orange browns to dark cool browns
- are some of the most schizophrenic!
Have a look at the PBr7 and PR101 section in this page of my website and you'll see what I mean. Some pigments cover a small range of colours, like PB29 Ultramarine, but others seem to cover a very large range not only of hue but also of characteristics. I'll look at PV19 here.
PV19 has a more rose version and a more violet version, though it also appears as a crimson (Alizarin Crimson Quinacridone by Da Vinci) and a dusky pink (rose Madder Permanent Hue by Art Spectrum.) Generally speaking, the more rose version will be called a Quinacridone rose/permanent rose colour where the more violet version will be called Quinacridone Violet or perhaps a magenta or mauve, but it does make it a little difficult to choose a colour based on pigments alone. As always, you need to look at the brand and the name to be sure of what you are getting.
